Thus it means is providedfor making: the motive power of the elevator entirely self-coxitoined and the elevator at self-propeller. [It will be seen that the senile circuit breakers. 27, l? and. stops 8, ind-s. hutonizilically render the n'iotoir inoperative at the proper time \vhiohever source of power is being used. Aleo not when the ltmtl'ery on theelevator is in use all the power circuit is confined. to the elevator. Another method for accomplishingthis phase of my" invention is Show in Fig. ii. In this modification an internal ooinblietion motor. E is supported from the under side of the elevator and is provided with a driving disk110. having a recessed center 112, such disk being adapted to be engaged by a friction roller 111 splined motion ,therethrough and carries on itsright.

hand end a bevel gear 116 adapted to'coop- .erate with a similar bevel gear 117 carried on the .lowerendof a shaft 118 supportedin suitable bearings as indicated and carriling at its upper end a crank 120. Fromtheconstruction ust described.1t 1s apparentthat when ,the gas motor- E is started, which may be accomplished in any well known manner, preferably with the roller 25,1511 opposite the recess 112, the roller 111 may be moved across the face of the disk 110 by turning the crank 120 and thus the shaft 9 maybe'rotated in either direction .atany desiredspeed as a result of which the elevator may be freely operated as de-' sired as theshaft 9 may bear the same rela tion to. the driving gears of the. elevator as shown in Fig.- l'orfin Fig."3.

In. Figs. 3 and 4 a form of gearing 1s shmvn 111 which the shaft 9 carries at Its end pinions 54C-adapted to cooperate with V the straightjtooth racks 1' and 4 secured to the guideways' g and g respectively. The shaft .9 also carries a bevel gear 63*ada'pted to coiiperate with a 'similaribevel gear 62 secured to thelowerend of shaft 50 and to the upper end ofwhich a similar bevel gear 60 is secured which is adapted to engage a sii'nila'r'bevel goal--59 secured upon the: shaft 121 totlieends of which pinions'5'7 and 58,

similar tG'and for the same purpose as pinions. 53 and 5A, are secured. The bearings of the several shafts just described are suit-,

ably supported by brackets 64:, 65, 5 5, 56 and 61, all of which except bracket 61, have members as 66 and 67 in Fig. 4:, extending on the rear side ofthe racks r, r? to maintain the'pi'nions 53, 57, 58 in ei'igagement at all .times'with such racks.

551- In Fig. -1 I have shown a signaling .sys.

. teni for calling the elevator from any of the several-floors as follows: Buttons 132, 133,.

134' are located on the differentfloors and serve to close a signaling circuit from any .60-suitable battery 13 located on the elevator car A", the current taking the following course. Battery B, wire 4:3, 'shoe'5 rail 3, "-wire 131', button 132, wire 130, trolley wire or rail 135, shoe 137, bell 136, back to bat- .tery E. Bell 136 is preferably of the vibrating type and the particular floor from which the signal is sent may be indicated by any suitable code of rings.

Mea'ns for lighting the elevator are indicated in Fig. 1, consisting of a lamp 138 bridged between wires 33 and 47 whereby light may be had as desired by turning the key connected'with the socket of such lamps.

As an alternate means of wiring for a light, a light- 138 is shown in Fig. 5 as bridged between the wires 4.8 and 19.

In Fig. 5 that part of my inventionis shown in which it is possible to automatic ally operate the elevator actuating mechanism from any floor and to cause the elevator 30 to stop at such floor. In this connection the operating gearing is not shown since it. is the same as that already described, and it being merely necessary to provide means for properly operating the motor M. The generator G, eed rails 3 and 4, battery B and switch ,0 .are also omitted for the sake o.t.' v clearness sinc'e obviously any or all of these aie iise'd in this connection as already described t'or Fig.1 and hence we'will assume that current is properly supplied to the elevator circuits by contact shoe 5 and returned therefrom to the generator by c011 tact shoe 6. e

To place the elevator in operative condition the switch 6 is closed thereby closing the field circuit of-motor M in the same manner already described excepting that from wire 48' in this case tliecurrent flows directly to shoe 6. 00 Buttons 1;", t t, t, t, t, are provided, two on each floor, the upper one on any floor beingfor the purpose ofbringing the elevator up to the corresponding floor, the

lower button being for the purpose of bring ng the elevator down to the corresponding floor. Buttons t and 29, are installed on the elevator so the passengers once in the elevator after it has responded to his operation from any floor, may move theelevatorup 'or down: respectively. I A

butt-0n t is provided to stop the elevator at any time desired. Assume that the but ton t has been depressed to bring the elevator to that floor. This closes contact 105 and atthe same time ,pushes out the sliding bar 0 against the slightest resisting friction of its support. The dotted lines to represent the thickness of the wall of the ele- -\'ator well. 'The closing of contact 105 .120 {closes the following circuit: shoe 5, wireAQ,

wire 93, bell 139, wire 140,.contact '73 of relay 1%., wire 92, winding of relay R",

Q This energiies relay R thus attracting its gra mes 74, 75 and 7 6 thus'closing contacts 70 and 71 and opening contact 7 2. The closing, of contact when depressed close contacts 103, 105 and 107 and thereby perform exactly the same 'function' elect rical.ly,that is, the energize.-

tion of relay R while the buttons t i t Sserve to close contacts 102, 104, 106 and thereby perform the same function electrically namely, the energization of relay R. The selection of the door in any case is accomplished mechanically by the engagement 1 of the particular stop. bar 1:, '0 o operated,

with the lever 20. It will also be noticed that the buttons 25 and t in closing contacts 84 and'83 serve the same purpose as t and 2% except that the contacts 83 and 84: are inside of contacts 86 and 87 and therefore the buttons t and maybe operated and the corresponding relays energized whether the contacts 86 and 87 are open or not.

Locking circuits are provided for the re 20 lays so that a single impulsefrmn any of the any operating condition circuit is at once opened and operating buttons may serve to establish and maintain a desired operating condition until such condition is interrupted either by the 'properstop bar or thestop button on the 25 elevator.

It will be noticed that both locking circuits are closed through contacts 85, 86, and 87 as a result of which, if button 6 is pressed for the relay locking the operating condition is' interrupted. If either contact 86 or 87 is open the elevator can only be operated in either direction by holding the buttons 13 t depressed since no locking circuit can decomplete with the contacts 86 or- 87 open. Thus the buttons t, t t furnish a means to "completely controlling the opera- ;tion of tile elevator from within the same. The energizing circuit of each relay is J complete through a back contact on the other iftolay so as to prevent the operation ot'either 5 relay when the other is energized, and it will be. noticed that this circuit is completed in each case through the bell 139, which, as here shown, 1s of the single stroke variety 1' and is used to give an audible indication on I'the elevatoi.', it of course being understood gthat if preferred a visible or a combined visible and audible signal :may be used in place of the bell 139., or, if preferred any of the well known electrical signaling or indicating devices be used, but preferably with moving contact between the push buttons on the different floors and the signal on the-elevator as, for example, described in these specifications.

' I do not. wish to limit myself to the exact construction or detail as shown in the drawlugs and specifications the entire invention is capable of many modifications.
